Source of material

To a suspension of 4-methoxyphenyl tellurium trichloride in benzene, 3-methoxyprop-1-yne was added. The obtained 15:12:1 mixture of isomeric dichlorides was reduced with a saturated sodium thiosulfate solution leading to a mixture of tellurides prone to separation by column chromatography. After separation, the major isomer was converted to the title compound by treatment with sulfuryl chloride in dichloromethane and crystallised from a mixture of dichloromethane and hexanes leading to colourless crystals. Crystals of (I) were obtained from recrystallisation from its CHCl3 solution. M. Pt.: 498–499 K. Micronalysis: Anal. C, 32.13; H, 3.19%.

Experimental details

The C-bound H atoms were geometrically placed (C—H = 0.93–0.97 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). Owing to poor agreement, one reflection, i.e. (3 9 1), was omitted from the final cyles of refinement. A correction for extinction effects was applied with a final co-efficient = 0.0078(5).

Comment

While not as well recognised as selenium compounds, tellurium species are known to exhibit exciting biological responses [7], [8]. Experiments [9], confirmed by molecular docking studies [10], indicate that cysteine proteases, such as Cathepsin B, are key targets for thiophilic tellurium compounds, owing to the presence of a cysteine residue in the active site. This is important as the inhibition of Cathepsin B results in the disruption of crucial cellular processes. It was in this connection that the title compound was originally synthesised among an extensive series of related derivatives [11]; experiments showed (I) not to be an effective inhibitor of Cathepsin B.

The molecular structure of (I) is illustrated in the upper part of the figure (35% displacement ellipsoids) and features a Te(IV) centre coordinated by ipso-C [Te—C1 = 2.114(3) Å], vinyl-C [Te—C8 = 2.118(3) Å] and two Cl Te—Cl1 = 2.4811(9) Å and Te—Cl2 = 2.5243(10) Å] atoms. The immediate coordination geometry about the tellurium(IV) centre is therefore, Ψ-trigonal bipyramid with the stereochemically active lone-pair of electrons occupying the third position in the equatorial plane. However, other close contacts are evident, such as an intramolecular Te⋯O(methoxy) interaction of 2.864(3) Å. Further, there is an intermolecular Te⋯Cl secondary bonding [12], [13] interaction with Te⋯Cl2i = 3.4229(12) Å for symmetry operation (i): x, 1/2 − y, 1/2 + z. The participation of the Cl2 atom in the secondary bonding interaction accounts for the elongation of the Te—Cl2 bond length compared with the Te—Cl1 bond. Taking into consideration the additional Te⋯O and Te⋯Cl interactions, the coordination geometry may therefore be described as Ψ-pentagonal-bipyramidal with the lone-pair of electrons occupying the fifth position in the equatorial plane. The result of the intermolecular Te⋯Cl interactions is the formation of a supramolecular chain with a zig-zag topology (glide symmetry) along the c-axis as shown in the lower part of the figure.

There are four direct literature precedents for (I), namely, the (4-MeOC6H4)Te[C(CMe2OH)=C(H)Cl]Cl2 [14], two conformational polymorphs of (4-MeOC6H4)Te{C[C(H)(OH)(CH2)5]=C(H)Ph}Cl2 [15] and (4-MeOC6H4)Te[C(Ph)=C(H)SPh]Cl2 [16], each of which features the same C2TeCl2 core as in (I), with a Ψ-trigonal-bipyramidal geometry, along with intramolecular Te⋯O or Te⋯S interactions.

In the crystal, the supramolecular chains are connected by methylene-C—H⋯O(methoxy) [C10—H10b⋯O1i: H10b⋯O1i = 2.58 Å, C10⋯O1i = 3.308(5) Å with angle at H10b = 132° for symmetry operation (ii) 2 − x, −1/2 + y, 3/2 − z] and methyl-C—H⋯Cl(Te-bound) [C11—H11b⋯Cl1iii: H11b⋯Cl1iii = 2.82 Å, C11⋯Cl1iii = 3.646(6) Å with angle at H11b = 145° for (iii): 1 − x, −y, 2 − z] interactions to consolidate the three-dimensional packing.

Additional insight into the supramolecular association was accomplished by calculating the Hirshfeld surface as well as the full and decomposed two-dimensional fingerprint plots employing Crystal Explorer 17 [17] and standard protocols [18]. The most dominant contacts to the calculated surface are due to H⋯Cl/Cl⋯H contacts, at 37.7%, followed closely by H⋯H contacts, at 33.8%. Other prominent contacts arise from H⋯O/O⋯H [9.3%], H⋯C/C⋯H [6.3%] and C⋯C [3.1%] contacts. The percentage contribution from Cl⋯Te/Te⋯Cl contacts is only 1.8% with Cl⋯Cl contacts contributing 1.7% but, at separations greater than the sum of the van der Waals radii.
